(Closed) Does your Duvet wrinkle?

We got a duvet from Restoration Hardware from our wedding registry. It just doesn’t look like it does in the store. The trick they use is to put TWO down comforters in their duvets to make it look so thick. Do any of you actually do that? I tried and I think it was way too heavy. So, with one in, sometimes the fabric will wrinkle and not look as good when the bed is made. Any suggestions?

Hmm mine doesn’t really wrinkle, but I do find that my down comforter doesn’t fully fill out my duvet cover after a few days–I need to like reach inside and pull it up to the corners. Is that what you mean?
